THOMAS W. LUGKE, OF CHICAGO, ILLINOIS.

VEHICLE-TIRE.

To all whom it may concern:

Be it known that I, THOMAS IV. LUCKE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Vehicle-Tires, of whichthe following is a specification.

My invention relates to improvements in vehicle tires, and moreparticularly to solid, resilient tires of the typeapplied to channelrims.

One of the salient objects of my invention is to provide a tire of thecharacter described, wherein there is employed no encircling wire.

A further object to provide a tire of the character described, which maybe applied to the rim withoutthe use of special tools, and which may bereadily and easily associated with its rim for use.

Another object of my invention to provide a construction of thecharacter described which will be simple, relatively cheap, andetlicient in operation. And still a further object of my invention is.toprovide fastening means for-a tire of the character described, whichwill operate to effect ively retain the plied, and which operate to holdthe tire at different points independent of each other.

In the drawing wherein l have illustrated an embodiment of my invention:Figure l is a plan view, with parts brokenaway, of a fragment of tireand channel rim. Fig. 2 is a transverse section on line 2-2 of Fig. 1,and, Fig.3 is a perspective detail of a coacting couple of fastmiingwires.

Throughout the drawing like numerals of reference refer alwaysto likeparts.

In the drawing 5 indicates a channel rim. preferably constructul ofmetal, and adapted to be applied to the wheel folly in any suitablemanner, such channel comprising the flat bottom part adapted to extendacross the folly; upturned and prefcraldy outwardly flaring side wingst5; and inturned edge beads or flanges.77, preferably having their lowersurfaces substantially horizontally disposed and their upper surfacesrounded or inwardly inclined.

8 indicates the tire proper whereof the body may be of any suitable(-mistiuction and configuration and which preferably is integrallyjoined with the wider base 9, shaped to snugly [it within the channelrim,

and to underlie the flanges 7 therein.

.\ssoc1ated,w1th the base and body, preferably by belng integrallymolded therein in process of construction of the tire proper, are theretaining wire structures, preferably arranged 111 couples shown at- 10,10.

when -in place 'lhesc structures comprise transverse wires of'lengthless than the full width of the base, disposed preferably in a generallyhorizontal plane, such wires extending each from a side face of the tirebase, transversely of the base to a point short of the opposite sideface of the base, and such retaining I. wires being so aranged that somethereof extend to one side face of the base while others extend to theother side face of the base. In the preferred construction each I suchstructure comprises two substantially parallel legs ll 1l, connected byan intoi gral connecting bar, or

or adjacent its middle a kink or deflection 13. In practice I preferthat such retaining wires be arranged asillustrated in the drawing, thatis to say, that two such structures 10, 10 be associated to form acouple, arranged, one with the kink 13 in its yoke 12 receiving a legitof the other member of the couple, and with one of its legs overlain bythe kink 13 of the other member of the couple. Such couples or retainingwires are disposed at intervals along thetire and each couple ope atesindependently of the others in performing its attaching functions inconnection with the channel rim.

In practice I prefer that the lateral extent of the couple, relative toyoke, 12, having at of each member the tire, be approximately threefourths of the transverse dimension of the tire base.

in use the tire, having embedded therein the attaching forcing it intoplace wit la pressure device, or by blows of a mallet. During suchoperation i t will be observed the attaching devicesforming a couple mayyield inwardly from the normal positions which they occu y when the tireis under its normal tension, tie body of rubber between the yoke 12 ofsuch ,member and the opposite edge of the tire base permitting suchyielding movement. I t will further be observed, however, that the yokesl2 and kinks 13 in the respective Wire members, prevent thelatter frombeing forced bodily into new positions relative to the tire body orbase, and afford such a firm rip for the rubber upon "the wires as to.insure thatwhen the rubber expands, after being compressed in theforcing on of the tire, the retaining wires will be forced outwardrelative to each other, so as to project beyond the sides of the tirebody and to engage under the flanges 7 of the channel rim.

It will be apparent to those skilled in the art, that the mechanicalembodiment of my ent of the United States, is:

1; Ina tire, the combination of a tire body, interlaced U-shapedretaining wires embedded therein extending transversely of the tirebody, and each having an end. projecting beyond the side edge of thetire bod of coacting retaining means comprising si e wings and inturnedflanges carried by said wings whercunder the projecting ends of thewires engage.

2. In a tire of the character described, a channel having upturned sidesterminating in inturned flanges, combined with a tire comprising a bodyortion, an extended base portion, and inter aced U-shaped retainingwires in the u per plane of said base portion, said U-shaped wiresextending transversefy of the tire in opposite directions through lessthan the full width of the tire base, and

at their ends disposed for engagement di- I rectly under the oppositeflanges of the channcl portion.

3. In a tire of the character described,'the

combination of a tire body, a channel rim having inturned flanges, 7;and retaining means in the tire comprising couples or! shaped wires,arran ed in interlaced relation with their free en s oppositelyprojecting,

one leg lying in the kink in the yoke of the other wire, said couplesbeing embedded inthe tire body with their free ends arranged forengagement under the flanges of the rim.

4. In a tire, the combination of, a tire body, retaining wires embeddedin said body I each having a portlon extending transversely r of thetire body with an end arranged in relation to one side of the body forengage-.

ment with a rim-part, said transverse portion of the wire stopping shortof the opposite side edge of the body and being suitably defiected toform an abutment which coacts with the solid rubber portion of the 4each wire having a kink in its yoke-part and body laterally beyond it toprevent permanent shifting ofthe wire in relation to the tire body,while permitting the rim-engaging end of the Wire to yield inward as thesolid cushioning part of the tire body is compiessed, and a coacting rimhaving inturned flanges for engagement with the rim-engag-
